Data Snoop Filter Back Invalidation Reduction Techniques

In the paper "Reducing Back Invalidation in Snoop Filter for Data", the authors propose techniques to reduce the number of back invalidations in the snoop filter during cache coherence operations. The techniques involve tracking the state of each cache line and selectively invalidating only the necessary ones. This reduces the overall invalidation traffic in the system and improves performance. The paper evaluates the proposed techniques using simulation.
